I've received an enquiry from Mary Houldsworth regarding field names in North Devon. She has received some assistance via the suggestions below. Would any list members have any other suggestions, or has she about got it right?
Gruttisheved - could be heved = head (as in head of valley or high place see below) plus gruttis gravelly, sandy soil or boulder strewn, so would be a prominent place with gravel or boulders.
Rixemer - is probably OE Rysc = ruch plus mere, pool or lake i.e. rushy pond or lake.
Sortestan - has defeated me so far the ending could be sta = stathir = farm, but it is a bit far south for that. Stathir is largely Scotland/ Isle of Man, Cumbria. Sortes or any variation of it I can't find.
Ringbrithescumbsheved - is relatively easy as it is obviously a place at the head of a valley heved = head, cumb = coomb Ring should be OE ring meaning circular as used in circular boundary, or possibly circular pond. Brithes could be a personal name or just possibly bridge so perhaps Brith's boundary or pond at the head of the valley.
